Grapevine plant named ‘IFG Ten’

ABSTRACT

A new and distinct grapevine variety denominated ‘IFG Ten’ is characterized by producing large, very crisp, oval, green, seedless berries borne on medium size clusters. The fruit ripen and are commercially harvestable in mid-season.

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘IFG Ten’.

BACKGROUND OF THE INVENTION

The new and distinct grapevine described and claimed herein originatedfrom a hand pollination of the USDA selection B31-164 and the Princessvariety (USDA variety non-patented) performed in May 2003. The resultingplants were planted into the field in April 2004. The present variety ofgrapevine was selected as a single plant in August 2005 and was firstasexually propagated by hardwood cuttings in December 2005. Theresulting propagules were planted during April 2006 near Delano, KernCounty Calif. and were found to reproduce true-to-type through at leasttwo generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new grapevine ‘IFG Ten’ is characterized by producing naturallylarge, oval, seedless berries having an occasional noticeable seedtrace. Berries are very firm and crisp in texture and ripen inmid-season. Fruits normally ripen in mid August, about with or justslightly later than the Thompson Seedless variety near Delano, Calif.

To the inventor's knowledge, the known variety which the new grapevinevariety is most similar to is its parent the Princess variety. ‘IFG Ten’can be distinguished from the Princess variety by having a more ovalshape as opposed to the more blocky, cylindrical shape of the Princessvariety. The flesh of the ‘IFG Ten’ is more crisp than the flesh of thePrincess variety and it is less prone to bruising and browning. The ‘IFGTen’ has superior storage ability compared with the Princess variety.The ‘IFG Ten’ exhibits much less excessive flower abortion at bloom ascompared with the Princess variety.

The ‘IFG Ten’ differs from the USDA B31-164 by producing yellow-greencolored fruits as opposed to the red fruits of the USDA B31-164 variety.
